This work is a collaboration <strong>of</strong> Aberystwyth University IBERS,<br />
the National Museum <strong>of</strong> Wales and the National Botanic Garden <strong>of</strong><br />
Wales. There were numerous questions put to Mike after his<br />
presentation. The one that I particularly remember was ‘How do<br />
you sex a bee?’<br />

NOTE Rhos pastures are flower-rich grasslands containing a mixture <strong>of</strong><br />
heathland and purple moor grass vegetation and providing a valuable<br />
habitat for endangered species <strong>of</strong> wildlife such as the marsh fritillary<br />
butterfly. Modern farming practices – including neglect, which allows<br />
the growth <strong>of</strong> scrub – have put this habitat increasingly at risk. The term,<br />
which ecologists now apply in other parts <strong>of</strong> Britain, derives from the<br />
Welsh rhos, meaning ‘heath’, and this is a habitat in which Ceredigion is<br />
well represented.<br />
Mike explained that thanks to this collaboration Wales hopes to be the<br />
first nation to complete the DNA barcoding <strong>of</strong> all <strong>of</strong> our species <strong>of</strong><br />
flowering plants – 1.143 <strong>of</strong> them – and to use this information as a basis<br />
for further investigation into plant behaviour. It is exciting to find that<br />
Ceredigion has played a major part in this research. The three ‘rhos’<br />
pastures monitored in the pollinator study were Glandenys, Fullbrook<br />
and Glyn yr Helyg – the latter two both classified among Ceredigion’s<br />
Sites <strong>of</strong> Special Scientific Interest (SSSIs).<br />
The colourful pie-charts from the study showed considerable seasonal<br />
variation as well as surprisingly different preferences in the tastes <strong>of</strong><br />
male and female bees – various Bombus species, whose similarities can<br />
confuse even the experts. And at this point we gardeners even<br />
encountered some actual plant names, albeit Latin ones: not all <strong>of</strong> us<br />
could remember, for instance, that the bee-favoureded Rhinanthus is<br />
yellow rattle and the Succisa species he mentioned is devil’s bit scabious.<br />

THE MAGIC OF ROSES<br />
LECTURE by GARETH DAVIES on 8 FEBRUARY<br />
All those who attended this talk must feel very much more<br />
confident about the roses in their gardens. Gareth’s obsession with<br />
roses started in the early 1960s, when he joined the Rhondda Rose<br />
<strong>Society</strong>, and the Hybrid Teas have always been his favourites.<br />
